George Takei stopped by TheDaily Show to promote the upcoming documentary, To Be Takei. Rather than discuss Takei's relationship with his husband or being on Star Trek, host John Stewart asked the veteran actor about his family’s time in a Japanese-American internment camp during World War II. What ensues is probably one of the most emotional and heart wrenching interviews ever on The Daily Show.
